Well,
Personal experience with ADS products is they are all junk!
That aside, changing injectors from the factory size will require a custom
chip, or a custom MAF calibrated to the size of the new
injectors. Dropping them in and not having the chip and/or MAF for those
injectors will cause the FI system to dump WAY too much fuel into the
engine, then start setting codes when it can't lean it out enough.

I recently bought a 93 4x4 Ranger with 4.0/automatic. My gas mileage
was about 11; after installing a new exhaust system, with free flow cat
and turbo mufflers, and installing a new thermostat, so the engine would
heat up (it was running real cool) and run at optimum temperatures, the
mileage is still low, about 12/13 (in 2wd).

Is this normal for this Ranger? Having owned 2 Broncos: 79 with
400/auto and 91 with 302/auto, I expect them to have bad mileage in this
range, but I thought the ranger would be about 15/16. That's what my
daughter's S10/auto 86 Blazer does.

Pls advise as to what mileage range I should expect, in 2wd...air temp
here in Va. mild (40s-60s) and average driving (about 2/3 in town, 1/3
on interstate). I really like the Ranger. Owning a 54 panel, 53/55
pickups, etc in a similar size group, it is easy to appreciate the quiet
in the Ranger.

Paul,
Good possibility the O2 sensors are going south and/or the MAF could be
dirty causing the truck to use more fuel.

I believe Pat Kunz is running the Summit injectors and swears by them.

I'm not sure what someone would mean by "wash"ing out your new injectors due
to the MSD6 and the Power chip. At issue with your engine mods is available
fuel. You don't say that you added headers, and you don't say that you
added a ported intake system or if you have the throttle body from the 86-87
Ranger/Bronco engines. Without those type of mods you probably haven't
affected your engine's capacity for air flow all that much. Thus your
current injectors can probably still deliver enough fuel to keep the engine
from running lean. If you had improved your engine's breathability
dramatically (headers and larger throttle body with intake porting) you
could run into a lean condition with the standard injectors(I believe they
are 15psi) as the physical design of the injector can't get enough fuel into
the cylinder for the given air volume in the required amount of time. The
Summit injectors are supposed to be much better and with an adjustable fuel
pressure regulator you can run their injectors up to 17psi to ensure your
engine doesn't run lean.

Of course, all of these mods would require a reburned Power Chip.

Hi All,
Here's one for ya...
My 97 Explorer V8 AWD has pulled a weird one on my 3 times now.
Running fine, stop at a light, light turns green, start off, get to about
5-10MPH, and it feels like someone turned off the key for about 1-1.5
seconds, then lurches forward and goes like normal.
All guages working fine during this, no CE light or stored codes.
It did it twice in 2 days about 3 months ago, and hasn't done it again
until tonight.
Checked out the TPs to see if it had a flat spot, but it is smooth and
linear on the scantool and on an ohmmeter. MAF is clean, O2 sensor
connectors clean and dry etc. Nothing unusual about the weather conditions
etc. (In fact the last time it did it, it was 90+ outside, tonight it was
55 or so.)
No distributor or I'd suspect the TFI module.
Any ideas?
Thanks,
Dave

I finally got my ranger fixed! The dealership service center replaced a
switch in the dash controlling the security and dome light. They also
said that they had to replace both of the switches in the doors do to
rust. Its nice to have a light again:)
however, i didn't think the switches would be rusty already in my 97
ranger. But, it was covered by the warranty luckily.

Well, these are THE summit injectors. We'll see what they can do. I have not yet
changed the headers, and I haven't messed with the throttle body because I was
told it would raise the peak torque point (2600 rpm) and since this is a 4x4
that sees the trails, I would like to keep peak torque a bit low.

What do you think?
